clear, and exact description, of the same, reference being had to the. accompanying drawings, nd t he em ef eference marked thereon, whichform a part ofthis.

specification h h It i a b e of my n nt o to prov de,

a window comprising a plurality of sections v1ew,.0f th e roller atIthe upper en of-the,

which are connected together in such a mane ner that they: 1 may all be simultaneously opened or partlyppened, and if, opened,

W fo t h wil hi h. p si ion. they y he slid tq ne ndJ -f t e ame 1 into any other position desired. I

It is further anobject of this to provide a window construction in which p tion f hewindQ opened, as desired, and regulatedand conil plur ty f. W d e hesare.;p ta y e manipulated as desired to open any v p I I r, ofthesash.f

I t is f r ore an obj ct flmyv nv tion to provide: a window construction in, which 5 as. many window sashesm ybe con nected together as desired, all of which have 1 a slidable connection at the topand bottom, and at their sides are interconnected to ad-., 1 just together, whereby the window may be trolled to admit the desired, quantity of air 1 or for other purposes, one,of which;is;the

cleaning of both sides of the Window panes from the inside of a building.

An important object of my inventionjs.

the construction of horizontally collapsible sashes which are adapted to Ibe Ifold ed together to occupy a small space and which,

whenlfolded, mayflbetadjustedu or slid intor any position in the frame.

Other and further important objects 0 this invention will be apparent from the disclosures in the specification and drawings. 50

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

but, of course, any number may be used. Sa1d sashes are hinged together along their ad acent inner vertlcal edges by means of leaf hinges 11, so that both may move to- 105 gether.

Rigidly secured by means of screws 12, on the upper surface of each sash at one end thereof is a plate 13, on. which a roller 14,

is rotatably mounted by means of apin 15. 110

The roller 14, fits in the channel member 6, and rests upon the supporting guides 7, while the pin 15, engages in the channel slot 8, as clearly shown in Fig. 7 Secured within a recess or notch by means of screws 16, to the bottom surface and near one vertical edge of each sash, is a plate 17, on whichis pivotally secured a block or slide member 18, provided with a slot 19, in which the rib 5, engages.

For the purpose of locking the sash in closed position, a spring lock 20, is attached to one or more of the sashes. The locking bolt of the lock 20, is disposed to engage in an apertured plate or keeper 21, secured upon the sill 2, thus firmly locking the sashes.

J ambs 22 and 23, are secured to the sides of the window frame to permit the stiles of the sashes to fit between said jambs when the sashes are in closed position to provide an anti-rattling and air-tight construction. A window screen 24, is shown mounted in the window frame on the inside of the sashes, and said screen is provided with a hinged section 25, by means of which the lock 20, may be released from the inside of the window to permit adjustment of the sashes. Y i

Fig. 11, shows a modified form of construction for adjustably mounting the lower end of a sash, and comprises a plate or track 26, secured upon the sill 2. Said plate has one margin thereof bent upwardly at rightangles and then outwardly to form an angle guide portion 27, adapted to engage in a 'bayonetslot 28, formed in a block or slide member 29, which is pivotally mount-' ed upon a plate 30, secured in a recess or, notch formed in the bottom of each sash.

In the modified form of mounting for the upper end of a sash, as shown in Fig. 12, the construction is practically the same as that shown in Fig. 7, with the exception that the roller 14, is replaced by a roller 31, provided with a peripheral groove or recess in which the supporting guides 7, engages, thus holding the roller 31, partly engaged in the channel guide 6, and partly projecting therefrom.

Fig. 13-, discloses another modified form of construction for the lower end of a sash,

, and embraces a plate 32, attached to the bottom of a sash. Said plate 32, has pivamount, and the rollers 14, track in. the

guide channel 6, while the slide members 18 slide on the rib 5, of the plate 4. When fully opened, the sashes assume the position shownlin dotted lines in Fig. 2. In thisposition, the sashes may be. slid. to either side of the window frame against either of the side frame members. understood that the sashes may be adjusted to any desired position with respect to one It will also be another and the frame, to effect any desired opening of the window.

The operation is very simple," and the rollers and guides form a smooth and easily adjustable device, readily permitting the sashes to be folded or collapsed with respect to one another to be slidably moved in any position in the window frame.

Iam aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my inventionz In a device of the class described, a window frame, a sash horizontally adjustable within the frame and guided above, a plate disposed at the sill and having an upstanding flange, and a block pivotally'mounted at" the lower edge of the sash and provided on its lower face with a groove to receive the upstanding flange, the opposite walls of the groove having a bearing engagement on the front and rear faces of the flange.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses:

ALPHONSE A. SEBASTIAN.
